I don't know where you get the 25% number from.Because all of those extra hits are also only .25% more likely.
Seriously the way the math works out you just add .25% to every number over 1, with 1 being .25%
So, if humans needed to roll a 16 to hit the enemy (because 10 in stat and no proficiency) they have a 25% chance to hit, hitting on 16 or higher.
Halflings get a 26.25% chance to hit. It is literally a 1.25% increase. That is incredibly minor.
Sure, it becomes more certain if you can somehow make 400 attacks against the same enemy in a round, but the difference is not going to turn the tide of the battle.
Humans: 400 attacks, 25%, get about 100 hits
Halflings: 400 attacks, 26.25%, get about 105 hits.
Halflings have an average of 12 dex and against an AC of 15, is hitting on 7 numbers or 35% of the time. So that's 140 hits without luck coming into play. At an average of 3.5 damage a hit, that's 490 damage. Your 3 demons had 50something hit points, it kills those 3 demons in 1 round three times over. And there wouldn't even be three wandering demons in the first place. Hell, at half damage they take out a pit fiend in 2 rounds
